Aqp9 gene expression was positively associated with markers of adiposity [body weight (r = 0.60, P < 0.001) or subcutaneous WAT/body weight (r = 0.44, P = 0.002)] and hepatic steatosis [liver/body weight (r = 0.69, P < 0.001) and intrahepatic TG (r = 0.28, P < 0.05)]. This evidence concerns the gene AQP9 and fatty liver disease.
